BUR-CRUSHING OR LIKE APPARATUS FOR USE IN CONNECTION WITH CARDING- ENGINES.

Specification of Letters Patent.

Application filed January 5, 1909.

Patented Feb. 13, 1912.

Serial No. 470,859.

To all whom it may concern Be it known that we, WILLIAM SHAW, of 71 Stoneleigh, Pollard Lane, Bradford, in the county of York, England, manager, J OSEPH BOWER, of 146 Heath Terrace, Bradford aforesaid, engineer, and FRED WILSON, of 98 Harrogate street, Bradford aforesaid, engineer, subjects of the King of Great Britain and Ireland, have invented certain new and useful Improvements in and Relating to Bur-Crushing or Like Apparatus Principally for Use in Connection with carding-Engines, of which the following is a specification.

This invention relates to improvements in bur crushing or like apparatus principally for use in connection with carding engines or the like, and has for its object the arrangement and application of simple and eflicient mechanism whereby the rollers of bur crushing or like apparatus are brought into or out of operation, as regards crushing, as may be desired, the operations being carried out more expeditiously and with less liability of sliver breakage than is the case with bur crushing or like apparatus, as now constructed. Further, by our invention, the wear on certain parts of the apparatus is considerably reduced, as is also the liability of injury to the operator while performing certain operations in connection with the apparatus.

In describing our invention in detail, reference is made to the accompanying sheet of drawings, similar letters indicating similar parts, in which,

Figure 1 represents a general elevation showing our improvement as applied to bur crushing apparatus. Fig. 2 represents an end view, and, Fig. 3 a detail.

In carrying out our invention, the rollers A and B are of the usual type, as are also the weights K and the attachment bars C to the top roller A.

Mounted in a suitable position toward each end of the apparatus, is a suitable cam, wedge bar, or the like D, and connected thereto is a lever L, by preference, shaped as shown. The levers L are in turn connected by a rod or bar E, in order that the cams or the like D may be operated together. The cams or the like D are provided with a flat face D normally in engagement with the vertically movable bearings A of the top roller A. Thus, as the rod or bar E is moved in direction of arrow in Fig. 2, the levers L will move and cause the cam or the like to lift some little distance, the top roller A. The distance the bar E will move, will regulate the lifter otherwise of the roller A. The weights being attached to the bars C which are in turn attached to the bearings A will be lifted with the roller. Thus, it is not necessary to remove the weights in order to operate the device, as is now the usual practice. worm or other suitable gearing may be employed to operate the before mentioned cam or the like. In some cases the rollers A and B are driven by friction rollers or disks, which are naturally subject to uneven wear and thus necessitate frequent repairs. In the present improvement, the said disks are It will be understood that discarded, and deep toothed wheels W and W substituted, and thus a positive drive is obtained. The lift of the roller A and wheel W being only a small distance, the teeth of the wheels W and W are not moved out of mesh. The said wheelsW and W are, by preference, provided with an oil tight case 0 in order to assist the smooth running of the gearing. Stops S are provided in any convenient manner, and positions, to keep the levers L in their required position, when the top and bottom rollers are not in contact.

What we claim as our invention is A bur crushing apparatus comprising a pair of uprights, a lower roller journaled in said uprights, an upper roller, gear wheels having deep teeth on said rollers meshing with each other, bearings for said upper roller vertically movable in the uprights, weight supporting rods connected with said bearings and passing downwardly through the uprights, Weights supported by said In Witness whereof We have hereunto set 10 rods, a cam rotatably mounted in each upour hands in the presence of two Witnesses. right below the movable bearing, said cam having a Hat face on Which the bearing rests WILLIAM SHAWV. in the normal posit-ion of the upper roller, JOSEPH BOVVER. a lever connected With each cam, and a bar FRED WILSON. connecting the free ends of said levers to- Vitnesses:
